CULVERT.

Specification of Letters Patent.

Patented Dec. 21, 1920.

'Application tiled November 3, `i919. Serial No. 335,381.

To ZZ whom t 'may concern.:

Be it known that I, RICHARD W. MC- QUEARY, citizen of the United States, residing at Granby, county of Grand, and State of Colorado, have invented certain new and Ausei'ul improvements in Culverts; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, and to the characters of reference marked thereon, which forni a part oi' this specification. i

This invention relates to culverts to be used particularly on mountain roads.

The object of the invention is to provide a Structure whereby water iiowing down ruts on inclined roads may be intercepted. Also, it is an object to deiiect water from the high side of the road to the low side at the Same time.

Briefly, the invention comprises a split cylinder adapted to be positioned in the roadbed with the slit uppermost to receive water from the crown of the road, the opposed edges of the cylinder having reversely turned horizontal tread plates adapted to lie flush with the road surface. At least one end of the cylinder is cut out at one side ior a short distance in order that the projecting side may be set across the ditch at the high side of the road to intercept water coming into the cylinder through the cut-out portion and to deflect it across the road.

In the drawing:

Figure 1 is a perspective, showing the use of the device;

F ig. 2 is an end view indicating the positioning of the same.

The culvert is in the form of a split cylinder 10, the split being indicated at 12 and being only two or three inches wide., so that traffic will not be interfered with. The tread plates 14 and 16 are turned back from the opposing edges of the cylinder at the split, these plates being iush with the crown of the road. As shown in the drawings, each end of the cylinder is cut back at the lower side to about the point indicated at 18, thereby forming a projecting corner or lip 20. The upgrade side of the cylinder at each end is cut on a line 22 in a vertical plane to leave an opening projecting upgrade. If desired, this cut may extend entirely to the lowest side of the cylinder, thereby partially sever-- tion tor sake of appearance. The culvert is preferably mounted in concrete 26, as indicated in Fig. 2, in order to make the device more substantial and rigid against trafiic.

l/Vhen both ends of the culvert are cut out as indicated at 18 and 22, the same structure may be used whether the high side of the road is on the right or on the lett, but it is obvious that only one end may be so constructed, requiring two designs of culverts cut out on opposite ends. l

As shown in Fig. l, the left end of the culvert is positioned against the bank of the ditch or hillside, while the opening on the opposite side extends upgrade to receive the water which is intercepted by the projecting side and deflected through the culvert to the low side. The grade of the road is indicated by the arrows. The cutout portion on the right-hand side has no Jfunction, as this is provided merely in order that the culvert may be used for slope in either direction. TWater coming down the road in the ruts will fall into the culvert through the slit 12 and run to the side of the road. lWater coming down the ditch on the high side flushes out any sand and dirt which is deposited in the culvert through the slit 12 and in this way the culvert is always kept clear.

These culverts are placed in the road at frequent intervals and in this manner washing on long stretches of rutty, downgrade road is prevented. In this manner road upkeep is materially reduced.

I claim:

l. A culvert comprising a split sheet metal cylinder, the split being located at its upper side to receive water from the crown of the road, said split being too narrow to interiere with traic, and oppositely extending horizontal tread plates connected with the edges of the cylinder at the split.

2. A culvert comprising a split thin walled cylinder, the split being located at its upper side to receive water from the crown of the road, said split being too narrow to intertere with traiiic, and oppositely extending horizontal tread plates connected with the edges of the cylinder at the split, said culvert being mounted in concrete and' said tread plates adapted to be positioned on the level of the road surface.

3. A culvert having one side Vat one end projecting beyondL the other side at that end7 said projecting side being adapted to be set in a ditch to delect down-*coming water said culvert at one'end projecting beyond the other side at that end and being adapted to be set in a ditch to deflect down-coming water through the culvert.

5. A .culvert comprising a split sheet metal cylinder, the split being located at its upper side to receive water from the crownV of the road, said split being too narrow to interfere with traiiic, one side of said culvert at one end projecting beyond the other side at that end and being adapted to be extended into a ditch to deiiect down-coming water through the culvert.

6. culvert comprising a split thin walled cylinder, the split being located at its upper side to receive water from the crown of the road, said split being too narrow to interfere with traffic, and oppositely extending hori- Zontal tread plates connected with the edges of the cylinder at the split, one side of said culvert at one end projecting beyond the other side at that end and being adapted to be extended into a ditch to deiiect downcoming water through the culvert.

In testimony whereof I affix my signature.

RICHARD W. MCQUEARY.
